An earthquake along the Sagaing Fault -- the same active strike-slip fault that runs the length of Myanmar -- dropped the valley floor and the water rushed in, drowning a village and its inhabitants. Whether the lake formed from subsidence or a landslide remains unclear, but the result is undeniable: Indawgyi Lake, stretching 24 kilometers north to south and 13 kilometers east to west in Kachin State, is one of the largest inland lakes in Southeast Asia. At 546 feet above sea level, ringed by over 20 villages of Shan and Kachin farmers, it fills a pull-apart basin similar in geological origin to California's Salton Trough.

The mechanics are precise: as the fault slips laterally, sections of crust pull apart, creating basins that fill with water. The same process shaped the Salton Sea ...

Indawgyi Lake: The Deer in the Grass

During biodiversity surveys in 2011, researchers discovered a population of endangered hog deer -- a species thought to have vanished from much of its historical range. Camera traps in early 2012 co...

Indawgyi Lake: Guardians of a Basin

Thu, 26 Mar 2026 00:00:00 GMT

Photo credit Winputoo, CC BY-SA 4.0. Conservation at Indawgyi began in the colonial era, when 62,000 hectares of forest were reserved for watershed protection. For decades, the lake's remoteness provided its own defense. That changed in the 1990s as new arrivals cleared forest and intensified fishing. The response h...
